CARB survey letter
A person on another site filled out the survey and the questions were:
What county is the car mostly used in
Approximate odometer reading
Approximate miles put on in a year
How frequently driven (the multiple choices went down from daily, weekly, to once a month, to a few times a year).
Where the car is kept - enclosed garage, car port, out in the open, etc.
What is done with the gas tank if the car isn't going to be used in a while, with multiple choices from "nothing", to draining the gas tank, and various choices involving adding fuel stabilizer.
